Oscoz Sanchez, Ibanezde Bilbao 6, Bilbao 1, Spain Filed Dec. 22, 1967, Ser. No. 692,754 Int.Cl. A47b 3/08, 1/04 U.S. Cl. 108-33 2 Claims ABSTRACT OF THE DISCLOSUREThe structure which is the subject of the present invention is, again,very simple, since it consists only of a maximum of two articulatedsupports, which are similar to a part of the supporting framework of anormal rigid structure.

With the aim of enabling the present invention to be better interpreted,in the attached drawings, complementary to the present exposition,various forms for its practical embodiment are represented; these formsare included merely by way of informative example, and are in no waylimitative of the invention.

In the said drawings, FIGURES 1, 2 and 3 show a perspective view ofastructure carried out in accordance with the characteristics of thepresent invention, which structure is shown in the completely foldedposition, with the structure semi-unfolded, and with the structure inthe position of supporting the table-top, the table-top being indicatedby dotted lines in the latter figure.

FIGURE 4 shows a plan view of the said structure, with its elementsfolded.

FIGURE 5 shows another structure with the same characteristics, butequipped with one single support framework.

As is shown in FIGURES 1 to 4, the structure is constituted by a fixedpanel 1, equipped with lateral leaves flanges on the internal faces ofwhich there are respectively articulated, by means of the hinges 4 and5, the support frameworks 3 and 2, which are constituted by a horizontalarm and a leg which projects beyond the upper part, by means of theprojecting piece 6, to form the point of support for the collapsibletable-top.

Both frameworks have their articulated end in angular form, in order toattain the sufficient length of hinge.

The situation of the articulation is such that they permit, as is shownin FIGURE 4, one of the frameworks to be situated against the fixedframework, and the other collapsed on the first. For this reason theframework 2 is longer than 3, so that in the unfolded position the legwill remain at the same distance from the fixed framework.

As has been said above, the folding structure can be constituted by asingle collapsible framework 7, as is shown in FIGURE 5, in which casethe open position is inclined with respect to the plane which the fixedframework forms.

The table-top can be equipped with locking means in order to fix thetable-top to the legs, which means may be simple check-pieces, orchannels or hollows into which there fit the projecting pieces 6 0f theframework.

Likewise, the fixed framework can form part of a piece of furniturewhich, in turn, can incorporate other folding frameworks, of the same orof a different type.

Having sufiiciently described the nature of the present invention,together with examples of the practical embodiment thereof, it onlyremains to be added that in the examples described it is possible tointroduce changes of material, form and arrangement, provided that suchalterations do not suppose any substantial variation in the object ofthe invention.

I claim:

1. A table structure comprising, a frame having a panel provided withlateral flanges extending at substantially right angles to the panel, anarm pivoted to the inside of one of the flanges with the pivot beinglocated near to the outer edge of the flange, a vertical supporting legat the outer end of the arm, the arm and its attached leg being of asize to enable them to be fitted within the frame between the flangesthereof, a second arm pivotally attached to the second flange and havingits pivot located at a point adjacent to the point of joinder of saidflange to the panel, said second arm carrying a leg at its end, thelast-mentioned arm and its attached leg being pivotal in a manner toenable it to be disposed within the frame between the flanges thereofand behind the first arm; the arms when disposed within the frame lyingone behind the other and inwardly of the outer limits of the flanges,both arms being capable, by movement on their respective pivots to causethem to project outwardly from the frame into substantially parallelrelationship and to then co-operate with the frame in supporting atable-top.

2. A table structure according to claim 1, wherein the pivots whichattach the arms to the panel are respectively located at opposite sidesof a transverse center line through the flanges, the arms and theirattached legs being disposed, when nested in the frame in parallelrelation to the face of the panel and in parallel relation to oneanother.
